I hope this person will read my post. 1st how old was he when you got him? How was he raised did you see the house the other dogs and the way he was raised? Did you get him from a reputable breeder?  
Yorkies should never leave their house for a new home untill at LEAST 12 weeks, the breeder should take the time to train him to be independent from the others. 
My puppies NEVER leave before the age of 12 weeks and having been taught to be alone as well as with the group. They are ALL raised in my home, 
I agree that training will help and you need to be persistant with the proper training. It will happen. Yorkies are VERY smart and will take over if you are not the one in charge. 
Good Luck and be paitent!
